Usually if for example the left side is favorable going upwind than that side will also be downwind (<- Does that make any sense?).
Well, a dumb blonde like me might think "that side" means the same side of the course will be favored both upwind and downwind.
Actually, if the left side of the course is favored as you are looking upwind, the left side of the course will be favored when you are looking downwind, which means you would head toward the side of the course OPPOSITE that which was favored on the upwind leg.
Probably not much more clear? <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
